Green power supply light blinking, computer won't start.
Recently, my computer was not turn off so in order to turn it off I unplugged the power cord from the computer. I came back in the morning to re-plug it to the back of the computer. When I did so, the green light that indicates if the computer is able to turn on or not was flashing instead of staying a solid green, and the computer will not turn on.

Re: Green power supply light blinking, computer won't...
A lot of those E-Machines used a small power supply (150 to 180 watts) and were known to have a failure rate. There is a way to check them by jumping across a two connector wires on the end that plugs into the Motherboard. Let me know if you want try this.

Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?
It sounds like the CPU is over heating. It probably has poor ventilation. Unplug the unit and open the side panel. Carefully vacuum all the dust inside. Be careful not to damage any electronics. You can use a small brush to loosen the dust before vacuuming. Good luck!
you bringing a marginal part or connection back up a working state. when it cools or voltage drops it goes to the non working state. hp power supplies are not good to begin with. replacing it will fix it till that one also fails
Try replacing the power supply, a blinking green light usually means the power supply is missing an output voltage. If you do that and you still get a blinking green light then the motherboard will need to be replaced.
As always verify all cords are plugged in properly. After that it sounds like you power supply went out. It is not that hard to replace. Make sure you unplug power cord. After you remove the pc cover, Usually you just need to unscrew 4 screws for the power supply. Somewhere on the power supply it should say how much watts it is. Anywhere from 200 watts and up. Just replace with exact wattage.
The green blinking light can mean there is a problem with the power supply.
Try unplugging the computer from the wall, and turning on the pc on switch.
After a few minutes, try plugging it back in.
If that does not start things up, you may have a bad power supply.
If the power supply is bad, these models take standard power supplies. You should get an ATX 350Watt or higher power supply.
They are easy to replace, unplug the power from the wall, disconnect all the cables inside the computer. Unscrew the four phillips screws outside the back of the computer where the power supply is attached to the case.
Remove and replace.
If you don't feel comfortable with this, a good local computer shop can help you out.
Regarding the blinking green light on power supply for hp a430n...I've had that happen as well when the computer is turned off for an extended period of time. It would not immediatly power up when plugged in to power. Hitting it and beating on the button didn't help either.
However, after calming down, I noticed that when I unplugged the computer that the light continues to blink, but gradually fades and goes out. So, I thought that since power supply holds a charge after being disconnected as can other components inside a computer that I would assume the converse: It needs to power up to "full charge" as well. In my case, I was right.
All I did was plug the computer in and leave it alone for about 20 to 30 minutes, go sit and cuss for a while. When I came back and checked it after that time, the front panel blue light was on and the green light on the power supply was glowing steady. The computer started right up! Thank goodness...stopped cussing.
If it hadn't, and I had tried all the resets listed above, I would have bought a new power supply too...but not this time!
